These plates were shot at 1:1 ratio, so head of model on plate is same as in real life. I'm not going to go into how effective aperture changes with bellows draw, that's for another time.
Fred the neighbor was as always kind enough to sit in for the sake of art and science.
Oh… On the plate made with the Vitax I think I forgot to turn one of the light back toward Fred, so lighting is a bit different there, but that doesn’t really affect what we’re looking at to much.
In interest of full disclosure – the glass on both 3A and Vitax is as good as it can be for 100+ year old lenses, while the 4A I have actually suffers from previous mistreatment, leaving it with a few significant scratches on back element and separation around the edge of front pair… I think the below results do show that, despite the flaws in glass, the image from it suffers very little if any at all.
